Listen music from web(safari app) through airport?

[achlioptas]

Hello,
I have an airport express and Leopard OS.
I would like to listen the music from various sites (eg grooveshark) directly to
my stereo, through the airpot.
Ofcourse my setup is ok and I can play music with Itunes in this way.
I just want to "aply it" to Safari.
Any Idea?
Thank you
